Not trying to hijack the thread but it's on a similar subject but can anyone say what kind of battery the C7 comes with?
Since some of the subsystems systems still operate after the car is shut off & yet it has to maintain enough juice for starting a V8 for the next drive cycle. I would imagine it may be more of a deep cycle battery as well as a starter. Maybe a hybrid style battery, has anyone look at the battery? Is it OEM to GM? Do we know GM uses for batteries?
Just thinking about an optima or oydessy, don't think a light weight lithium would be best in the situation.

This option was already on the car we bought but personally, I would not have ordered it. We have battery tenders on our jet skis at home that work well and were cheaper than the Corvette battery tender.

Could use alligator clips but if you were using the charger often might consider using the two wire connector with the ring terminals that came with the CTEK. Recently on another thread, relative to powering an auxiliary device, it was mentioned not to remove the nut on the positive terminal, the one powering the fuse panel but add a ring terminal and another nut on top. There was a picture with the plastic cover on and a wire and fuse coming from underneath.

I have the C-Tek MU4.7, and like it better than the 3300 because it has status lights showing the state of battery charge - it is about $10 more than the 3300.
The cigarette lighter attachment was an additional $9. All in it was $64.

I have had more than One (1) CTEK trickle / maintainer go bad. When they do if not found
in a timely manner they will kill the battery. A clicking sound emanating from the CTEK is
a indication of a bad charger. If the charger is plugged into the car but not plugged into
the 120V source it will kill the battery.
